we m me -ate, Yeas- E I L ii -M mes? FOR ac es are. qu te Q9PEQ To all whoz n it may concern:

Be it known that I, O'r'ro L. Hi v'rz, a a

citizen of the United States, residing at But talo, in the county of Erie and State of New York, have invented new and useful Improvements in Vehicle Attachments to!" Motor and other Cycles, of which the tollowing is a specification.

This invention relates to a vehicle attachment for motor and other cycles whereby .an ordinary two-wheeled motor driven cycle may be readily converted into a motor car capable of carrying a number of persons easily and conveniently and on a wheel base which rests on the ground at four points The object of this invention is to provide an attachment ofthis character which is,

simple and durable in construction, which can be readily attached to and :emoved from various types of motor cycles new found on the market, which is neat and ,attractive in appearance and which permits of carrying a greater number of passengers or load with the same degree of comfort and efficiency as an ordinary automobile,

While th spai'ticular mete cycl s cap bl f recause my imp o e v hi e t me t it i is to, be understood that my invention is capable of use with any other suitable form of motor cycle. r

The main f am v t h l a tac is generally constructed inthe form of the letter U the transverse part of which .is adap ed t e a ra d, in re r f t motor cycle while t e branches or legs thereof are adapted to project forwardly and. lengthwise on opposite sides of the motor cycle. A shown in h r ings h trans part of the frame of the vehicle attachment comprises a transverse axle or. cross piece 9 and each of the branches comprises an inner lo gi u inal ba 10 xt din or a dly from the cross piece 9, and an outer longitudinal bar 11 which is arra ged adjacent to the outer side of the inner bar but is spaced apart therefrom and is connected at its rear end with the cross piece .9 while its 15 of the vehicle attachment are journaled. I Upon this frame of the vehicle attachment [is mounted'a body'which may be of, any suitable construction for carrylng passengers v or merchandise. As shown'in the-drawings,

this body 16' is constructed for the trans ably connected with the lower part of the "lower motor cycle frame bar 2 by a clampportation of passengers and has'a seat 17 which is wide enough to accommodate a number of persons and enable the same to look forward on opposite sides of the motor cycle with which the attachment is connected. This body is preferably supported yieldinglyupon the main frame of'the vehicle attachment, this being accomplished for instance by means of front and rear springs '18, 19- connecting the front and rear ends of ,thebody with'transverse cleats 20 onthe front and rear parts of the inner and outer.

longitudinal bars of the vehicle attachmentframe. 7

To permit of readily connecting this vehicle attachment with the motor eycle'frame or disconnecting the same therefrom the lower bar 2 of the main frame of the motor cycle is provided with a bracket which is preferably so constructed thatthe same may remain permanently connected wlth thls bar. Inasmuch as the latter 1s usually lncllned forward more orless in different motor cycles the means for coupling this attachment with this bar'are so designed that they are ca- 'pable ofadjustment to suit the different angles ofsuch bars in different makes of motor cycles. Although this bracket may be variously constructed that shown' in the attaching bracket is provided with two reardrawings is suitable and is constructed as follows 21 represents a cross bar adapted to be arranged in front of the lower part of the lower motor cycleframe bar 2 and 22,22 two braces which are connected, at their lower ends with this cross bar near opposite ends thereof and provided at their upper ends with couplingeyes 23, 23; said braces manner that, the latter may be turned in a vertical plane to the desired position relatively to. the motorcycle frame in order to bring these parts inproper position for connecting the same. In its preferred form'this coupling device comprises two body sections 'or blocks 24, 25 which have thelroppos'mg sides recessed to engage with opposite sides with the lower frame bar 2 and held in en "one of the clamping body sections, pref 7O erably the front section 24:, is provided with laterally projecting pivot pins or coupling trunnions '27" which receive the eyes 23 at the upper ends of the bracket braces 22, these eyes being retained on these pivot pins by. means of screw nuts 28 applied to the threaded'ends of these-pivot pins or by any other suitable means v The cross bar 21 ofithe bracket'is detaclr' ing device which comprises an intermediate block 29 provided on itsopposite sides with grooves or seats 80, 31,arranged at right angles to eachother and adapted to receive the proximate sides of the cross bar 21 and the motor cycle bar 2, a front block 32 pro- 'v'ided'on its inner side with a groove or seat 32"engaging with the, front side of the bracket'cross bar 21, a rear block 33 provided onits inner side with a groove or seat I 3 1 engaging with the rear side of the motor cycle'bar 2' and clamping bolts 35 connecting these several clamping blocks on opposite position preparatory to being fixed on the ,motor cycle frame. a

At opposite ends the cross bar 21 of the wardlyprojecting arms 36 to which the side branches of the vehicle attachment are adapted to be connected. These attaching arms are immovable after being once set but are capable of adjustment in a vertical'plane about the cross bar 21 as an axis for the purpose of bringing the rear ends of these arms I which project rearwardly from the cross bar '21 into the proper" position. The preferred mean'sfor effecting this adjustn'ient consists in'providing the front ends of the attaching 2 arms 36 with sleeves 37 which are mounted on the opposite ends of the cross bar 21. so

' clamping screws 38" whereby they may be rigidly secured to this cross bar after they have been adjusted to the desired position. v

The connection between the branches of the vehicle attachment and the motor cycle frame is preferably effected by meansof machine.

springs so as to permit the vehicle: attachment and the n otor cycle frame tornove vertically independently of each other as they followithe uneven surfaces of the road or the ground over-which they travel. This spring connection is preferably so constructed that the motor cyclelfmme end the vehicle attachment frame are :incapable of moving 7 horizontally or laterally relatively :to each other, thereby maintaining these 'parts ain proper ialinement to cause the 'brancheswith the attaching bracket The leaves of each of these springs are arranged with their fiatsideszhorizontallly'so that they :are capable of being flexed only in a vertical direction but are rigid in-a horizontal directionboth laterally :and lengthwise re1a- :tively to the motor cycle and the vehicle attachment. :In thepreferred form of-each of these springsyasshownv in Figs. 1, 2, 5 and 8, the same, comprises a: main spring leaf 39, an anxlliary front'spring leaf 40 arranged 7 over; the front part of the m-ainleaf, an attaclnng plate .41 arranged over the front part of the-auxiliary from leaf, clips 42 connecting the attaching "plate with the front ends oflthe main springileafia-nd front auxiliarywspring leaf, aspacing'plate or washer d3, arranged nponthe rear part of thezmain springleafltwo rearaauxiliary spring leaves 44 arranged with their-rrear ends .over the spacing plate ,or washer :43 while their front endslap over the frontcauxiliary leaf,-and clips 45 connecting the rearends of the main spring leaf,-spacingx;plate 43 :and rear auxiliary springleaves. Bythis means a spring is produced which-possessesthe requisite re silience in a vertical direction for allowing the motorcycle andthevehicle attachment toriseand fall independently of ,eachother and yet form a rigid connection between the vmotorcycle and the vehicle vattachment to properly supportthe load imposed upon the latter and also retain these main members in the proper lateral and longitudinal JPOSltlOll relatively to each other. Inasmuch as the available placefor connectingthc vehicle attachment with the motor cycle varies slightly it is desirable to make the connection be- :tWeen the: branches of the vehicle attachment and the motor cycle attaching bracket adjustable in the direction ofthe length of .the For this purpose the front end of each connecting-spring-is dctachably connected with this bracket and its rearend' is connected with the front endofth'e companion abranch -c .;,the vehicle attachment frame so as to permit the latter to be adjusted lengthwise relatively to the motor cycle; The preferred means for accomplishing this purpose which are shown in the drawings comprise a bolt 46 whereby the front end of the attaching plate 41 is detachably connected with the rear end of the attaching or coupling arms 36 on the respective side of the motor cycle, and an adjustable connection is provided between the rear end of'this spring and the front end of the companion branch of the vehicle attachment comprising an upper clamping block 47 interposcdbetwecn the underside of the rear end of the main spring leaf and the front part of the upper side of the inner bar ofthe adjacent branch of the vehicle attachment, a lower clamping block 48 engagingwith the underside of said bar at the front end thereof. While these clamping blocks are loose the same and the inner longitudinalframc bar 10 may be moved freely lengthwise relatively to each other for bringing the vehicle attachment to the proper position after which the clips 45 embracing these blocks and the rear ends of the members of the companion leaf spring will socurely hold these parts in position relatively 'to each other.

In order to aid the leaf springs in holding the vehicle attachment against lateral movement relatively to the motor cycle means are provided which cooperate with the rear axle 49 of'the rear driving wheel of the motor cycle. This axle is fixed on the rear fork of the motor cycle and the means shown in the drawings for cooperating with this axle to prevent lateral movement of the vehicle attachment are preferably constructed as follows:

a The opposite ends of the rear motor cycle axle is provided with guide heads each of which comprises a horizontal shank o0, an internally screw threaded socket arranged at the inner end of the shank, a cross piece 52 arranged at the outer end of the shank and a pair of bearing rollers 53 arranged at opposite ends of the cross piece. The socket 51 engages with an external thread on the adjacent outer end of the motor cycle axle l5) and is held iu'its proper position by means of a clamping nut 5i arranged on the axle and engaging with the inner end of the socket, or by any other suitable means, so that the bearing rollers 53 have their axes arranged horizontally and at right angles to the axis of the motor .cyclc axle. represents a guide channel mounted on cachinner bar 10 of the vehicle attachment frame between the front and parallel and have their open sides facing each other. This guide channel is connected with the adjacent inner bar-l0 preferably by means of a horizontal transverse pivot or bracket 58 secured to the adjacent part of said bar 10 so that this guide channel can swing in a vertical plane lengthwise of the vehicle attachment. The rollers of the adjacent guide head engage with the inner side of the grooves of the guide channel, whereby the vehicle attachment andthe motor cycle are guided in .their vertical movement relatively to each other but are held against movement relatively to each other in a horizontal lateral direction relatively to these parts. Distortion or displacement of the motor cycle-and the vehicle attachment are therefore avoided and a proper trailing, of the vehicle attachment behind the motor cycle .is' assured when the same is in use. Instead of the guide channels 55 and the heads engaging therewith for holding the motor cycle and vehicle attachment in place laterally relatively to each other this result may be obtained by connecting opposite ends of'the rear cycle axle 49 by springs 59 with standards or sup:-

ports 60 on the adjacent parts of the inner and outer frame bars 10, 11, as shown in Fig. 12. When it is desired to use the motor cycle without the vehicle attachment it is only necessary to detach the bolts 46 and slip the 4 guide heads of the rear axle out of the guide channels 55, thereby leaving the motor cycle free to be used in the ordinary manner. The motor cycle and the vehicle attachment can be as easily reassembled when it is desired to accommodate a larger number of'passengers than can be carried on the motor cycle alone. By this means the utility of a motor cycle can be largely increased and used conveniently for business or other purposes without the vehicle at tachment as well as for pleasure or other purposes in connection with the vehicle attachment. The expense of maintaining the motor cycle can also be readily adjusted in accordance with the work which the same is called upon to perform, less fuel being used when the motor cycle 1s used alone for but a single passenger, and more fuel being used only when added passengers are carried upon connecting the vehicle attachment to the motor cycle.

Aside from being very strong and durable this particular design of vehicle attachment in nowise interferes with the working of the parts of the regular motor cycle so that no re-adjustment of the same is required when converting the same from one use to another. Owing to the compact arrangement of the parts and the disposition of the same around the motor cycle in the manner indicated in the drawings a neat and finished appearance of the vehicle as a whole is presented.
